---++SDD Part 0: Introduction and Primer to the SDD Standard
---+++4.4 Elements of structured summary data in SDD.
A coded description requires three essential items: the names of the taxa being described, the terminology (characters and states) used to describe the taxa, and the coded descriptions themselves
<img src="%ATTACHURLPATH%/coded_data.gif"/>
An SDD instance document for coded summary data has the basic structure shown in Example 4.4.1.
---++++Example 4.4.1 - SDD structure of coded descriptions
<table bgcolor="#ddddff" border="0" width="80%" cellpadding="5" cellspacing="5" style="border-collapse: collapse" bordercolor="#111111">
<tr>
<td>
<verbatim>
<Datasets>
<Dataset>
<TaxonNames>
... provides a list of the entities (usually taxa) described
</TaxonNames>
<TaxonHierarchies>
... optional element to describe relationships between entities
</TaxonHierarchies>
<DescriptiveTerminology>
... provides the terminology and ontology used to describe the
entities (see DescriptiveConcepts, SddCharacters, CharacterTrees)
</DescriptiveTerminology>
<CodedDescriptions>
<SummaryData>
... the actual descriptions
</SummaryData>
</CodedDescriptions>
<MediaResources>
... optional element providing media (images, video, audio etc.) associated with
any of the above
</MediaResources>
</Dataset>
</Datasets>
</verbatim>
</td>
</tr>
</table>
Optional elements allow the taxa to be arranged into a hierarchy, and the recording of media files (images etc) for taxa or characters.
